There are five vertices on a pentahedron. The word penta means fivewhich is based on the 5 edges and 5 diagonal faces that it has. * * * * * Apart from the fact that penta me…ans five, the rest of the answeris utter nonsense. Typical of answers from "The Community", I amafraid.5 vertices 5 faces 8 edges (MORE)

A pentahedron in the form of a square pyramid has 5 vertices and in the form of a triangular prism has 6 vertices.

In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex). Like any pyramid, it is… self-dual. The regular pentagonal pyramid has a base that is a regular pentagon and lateral faces that are equilateral triangles. It is one of the Johnson solids ( J 2 ). Its height H , from the midpoint of the pentagonal face to the apex It can be seen as the "lid" of an icosahedron ; the rest of the icosahedron forms a gyroelongated pentagonal pyramid, J 11 . The 92 Johnson solids were named and described by Norman Johnson in 1966. More generally an order-2 vertex-uniform pentagonal pyramid can be defined with a regular pentagonal base and 5 isosceles triangle sides of any height. (MORE)

The triangular faces which rise from a square base are 4 in number, whilst from a pentagular base there are five triangles rising to meet at the apex, so the4 answer is "One m…ore". (MORE)

It could be a pyramid with a quadrilateral base or a triangular prism. There are, of course, other related shapes that it could be.

Five faces (it is a 3 dimensional shape). A four sided pyramid is a pentahedron. (penta- means five, -hedron means sides)

In the form of a quadrilateral based pyramid, it has 5. In the form of a triangular based prism, it has 6.

A pentahedron can be a triangular prism or a quadrilateral based pyramid. The answer will obviously depend on which one. Furthermore, it will depend on whether or not its face…s are regular.

Yes because a triangular prism has 5 faces and also it has 9 edges and 6 vertices
